Description

Technical Field

[0001] This utility model relates to the field of PE film production, and in particular to a waste recycling device for PE film production. Background Technology

[0002] During the production of PE plastic film, a large amount of scrap material is often generated. This scrap material is usually cut off by cutting equipment and is considered waste. It is generally placed directly into recycling bins for recycling. However, after a period of time, the scrap material will fill up. This is because the scrap material is relatively loose and takes up a lot of space. It is necessary to frequently squeeze the scrap material inside the recycling bin or frequently process the adhesive material inside the recycling bin, which greatly delays work efficiency. Therefore, in order to solve the above problems, a waste material recycling device for PE film production is proposed. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a waste recycling device for PE film production. When the film scraps are piled up, the crushing motor is started to drive the rotating shaft to rotate, thereby causing the crushing blades to crush the film scraps in time, ensuring that the recycling bin can continuously hold film scraps.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waste recycling device for PE film production, the recycling device consisting of a hollow chamber recycling box and a feeding mechanism, the feeding mechanism being installed on the top of the recycling box and used to press down the film waste;

[0005] The bottom of the recycling bin is equipped with four support bases at the four corners. The bases contain adjustable components, and the top of the adjustable components is equipped with a crushing motor. The main shaft of the crushing motor is fixedly connected to a rotating shaft, and the other end of the rotating shaft is fixedly connected to evenly distributed crushing blades.

[0006] Furthermore, during the crushing process of the film waste, a sliding sleeve is installed inside the recycling bin to ensure that it slides up and down with the bottom of the recycling bin, and the inner side of the sliding sleeve is fixedly connected to the rotating shaft to move up and down with the rotating shaft.

[0007] Furthermore, the adjusting component includes a hydraulic rod installed inside the base, and the free end of the hydraulic rod is fixedly connected to a mounting base, and a vertically arranged crushing motor is installed inside the mounting base;

[0008] A vertically mounted guide rod is slidably connected to one side of the mounting base, and the top of the guide rod is fixedly connected to the recycling bin.

[0009] Furthermore, a discharge pipe for discharging materials is also installed on the side of the recycling bin.

[0010] Furthermore, the bottom of the feeding mechanism is provided with a feeding sleeve that is fixedly connected to the recycling bin. An installation plate is installed on one side of the top of the feeding sleeve. A vertically arranged feeding motor is fixedly connected to one side of the installation plate. A threaded shaft is fixedly connected to the end of the main shaft of the feeding motor. A threaded sleeve is spirally connected to the outside of the threaded shaft. An extrusion plate is fixedly connected to the bottom of the threaded sleeve. The outside of the extrusion plate is slidably connected to the outer wall of the installation plate.

[0011] Furthermore, an installation frame is installed on the top of the extrusion plate. An air pump for exhaust is installed inside the installation frame. The output end of the air pump is connected to an air pipe, and the other end of the air pipe is connected to a hollow disc. The bottom of the hollow disc is connected to evenly distributed nozzles, and the bottom of the nozzles is convex relative to the bottom of the extrusion plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. During production, film scraps are directly put into the recycling bin for collection. When the recycling bin is full, the crushing motor is started to drive the rotating shaft to rotate, so that the crushing blades can crush the film scraps in time, ensuring that the recycling bin can continuously hold film scraps.

[0014] At the same time, the hydraulic rod is activated to move the mounting base upwards. This allows the crushing motor to drive the rotating shaft and crushing blades upwards. The crushing blades are positioned at different heights inside the recycling box, which can fully crush the film scraps.

[0015] 2. Furthermore, when the film scraps enter the recycling bin through the feeding sleeve, the extrusion plate can squeeze the film scraps into the recycling bin by moving downwards, ensuring that the film scraps are thoroughly cleaned. Also, some film scraps may not fall easily because their sides are in contact with the inner wall of the feeding sleeve or the inner wall of the recycling bin. In this case, the air pump can be started, and the air is discharged through the nozzle to press down the film scraps, ensuring that the crushing blades crush the film scraps.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0020] A waste recycling device for PE film production, such as Figure 1-2 As shown, the recycling device consists of a hollow chamber recycling box 8 and a feeding mechanism 9. The feeding mechanism 9 is installed on the top of the recycling box 8 and is used to press down the film waste.

[0021] The bottom of the recycling bin 8 is also equipped with a base 1 for support at the four corners. An adjustment component 3 is installed inside the base 1. A crushing motor 4 is installed on the top of the adjustment component 3. A rotating shaft 5 is fixedly connected to the end of the main shaft of the crushing motor 4. The other end of the rotating shaft 5 is fixedly connected to evenly distributed crushing blades 7.

[0022] It also includes a sliding sleeve 6 installed inside the recycling bin 8 during the crushing process of the film waste, which ensures that it slides up and down with the bottom of the recycling bin 8, and the inner side of the sliding sleeve 6 is fixedly connected to the rotating shaft 5 to move up and down with the rotating shaft 5.

[0023] During the production of PE plastic film, a large amount of scrap material is often generated. This scrap material is usually cut off by cutting equipment and is considered waste. It is generally placed directly into a recycling bin for recycling. However, the scrap material will eventually fill up after a period of time because it is relatively loose and takes up a lot of space. It is necessary to frequently squeeze the scrap material inside the recycling bin or frequently process the adhesive material inside the recycling bin, which greatly delays the work efficiency. During production, the film scrap material is directly put into the recycling bin 8 for collection. When the film scrap material fills up, the crushing motor 4 is started to drive the rotating shaft 5 to rotate, so that the crushing blades 7 crush the film scrap material in time, ensuring that the recycling bin 8 can continuously hold film scrap material. The sliding sleeve 6 is designed to prevent the crushed material from falling into the gap between the sliding sleeve 6 and the recycling bin 8.

[0024] The adjusting component 3 includes a hydraulic rod 301 installed inside the base 1, and the free end of the hydraulic rod 301 is fixedly connected to a mounting base 302. A vertically arranged crushing motor 4 is installed inside the mounting base 302.

[0025] A vertically arranged guide rod 303 is slidably connected to one side of the mounting base 302, and the top of the guide rod 303 is fixedly connected to the recycling bin 8.

[0026] The side of the recycling bin 8 is also equipped with a discharge pipe 2 for discharging materials.

[0027] The hydraulic rod 301 is activated to move the mounting base 302 upward. At this time, the crushing motor 4 can drive the rotating shaft 5 and the crushing blades 7 to move upward. The crushing blades 7 are at different heights inside the recycling box 8, which can fully crush the film scraps. The vertically set guide rod 303 installed on the side of the mounting base 302 can ensure that the mounting base 302 moves up and down stably, and ensure that the crushing motor 4 drives the rotating shaft 5 to move up and down, so that the crushing blades 7 can crush the waste in multiple directions.

[0028] The bottom of the feeding mechanism 9 is provided with a feeding sleeve 901 that is fixedly connected to the recycling box 8. A mounting plate 902 is installed on one side of the top of the feeding sleeve 901. A vertically arranged feeding motor 903 is fixedly connected to one side of the mounting plate 902. A threaded shaft 904 is fixedly connected to the end of the main shaft of the feeding motor 903. A threaded sleeve 905 is spirally connected to the outside of the threaded shaft 904. A pressing plate 906 is fixedly connected to the bottom of the threaded sleeve 905. The outside of the pressing plate 906 is slidably connected to the outer wall of the mounting plate 902.

[0029] The top of the extrusion plate 906 is also equipped with an installation frame 907. An air pump 908 for exhaust is installed inside the installation frame 907. The output end of the air pump 908 is connected to an air pipe 909. The other end of the air pipe 909 is connected to a hollow disc 910. The bottom of the hollow disc 910 is connected to evenly distributed nozzles 911. The bottom of the nozzles 911 is convex compared to the bottom of the extrusion plate 906.

[0030] When the film scraps enter the recycling bin 8 through the feeding sleeve 901, the feeding motor 903 drives the threaded shaft 904 to rotate, and the threaded shaft 904 drives the threaded sleeve 905 to move. At this time, the extrusion plate 906 can move down. To ensure that the extrusion plate 906 moves down stably and does not rotate on its own, one side of the extrusion plate 906 contacts the side of the mounting plate 902. This ensures that the extrusion plate 906 has no space to rotate on its own. The extrusion plate 906 can squeeze the film scraps into the recycling bin 8, ensuring that the film scraps are fully cleaned. Some film scraps are not easy to fall because their sides are in contact with the inner wall of the feeding sleeve 901 or the inner wall of the recycling bin 8. At this time, the air pump 908 can be started, and the air is discharged through the nozzle 911 to press down the film scraps, ensuring the crushing effect of the crushing blade 7 on the film scraps.

[0031] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
